A key challenge in quantum computing involves dealing with errors which may arise from environmental noise or imperfections in the hardware. Error mitigation and correction strategies are essential to the development of practical quantum computing devices. In recent years, photonic quantum computing has emerged as a promising platform for quantum computing and demonstrating a genuine quantum advantage. Quantum states of light (QSoL) are robust to environmental noise and can be easily manipulated and measured using simple optical components at room temperature. Additionally, QSoL can be transmitted over long distances using optical fibres, which makes them an attractive option for quantum communication and networking.
